Just two cents more...
...on the D3's. I have them & they are great in the rain...if that's important for you. It was for me & I'm not sorry at all that I bought them. The wet grip & directional control and the resistance to hydroplainning is very satisfying.
If you don't plan on rain use then they are a bit noisy due to the pattern being so open. They also are a bit darty on rough or uneven pavement so you have to pay attention. The expansion joints and wear patterns in roads, the ones parallel to travel direction, grab the tire & you have to correct, in the dry & not so bad in the wet.
They are outstanding, JMHO, in going thru standing water though. The feel doesn't leave the steering wheel if you hit a puddle or are on a road with alot of water on it. They give a very secure & controlled feeling at sane speeds, say below 80 in a steady rain that leaves water on the road in sheets. The breaking & accleration response is also very good in those conditions. Overall a very good rain tire that works well in the dry. I can't say anything about how they hook up from a standing start but they will break loose a bit on dusty concrete in a hard run thru 1st & 2nd otherwise they have great straight line grip to me. To me they seem to be very good in dry road handling if you get "enthusiastic" in the twisties. Although I'm not qualified to really speak about that except to say they seem to have more than I have in ability and nerve. They don't break away suddenly even if you make a wrong choice about what to do going into a cornner. They let you know in plenty of time that you messed up. You can feel a slight slide and the chassis start to twist and unload a corner of the car and even a little squeal. I think it's the tire's way of letting you know you made a bad decission. The nice thing is that they don't break away quickly. They give you some time to back out without snapping loose.
Sorry to be so long.
Good luck in your search!
